Cost & commercial
A low price is only a saving if the job is done. With duct cleaning, the risk of cheap is not disappointment - it is grease left where fires start, insurance that will not pay, and a certificate that falls apart when it is examined.
The short answer
There is nothing wrong with wanting a good price. The problem with a cheap duct clean is what tends to come with it: a partial job that leaves grease in the runs, no real verification, and a certificate that implies more than was done. If that surfaces - and it usually surfaces at the worst moment - you pay to have it done again properly. The saving evaporates and takes your time and peace of mind with it. This page is about weighing that gamble honestly.
What you are actually gambling
First, fire safety. Grease left in concealed ductwork is exactly the fuel a kitchen fire needs to spread, and a canopy-only clean leaves the most dangerous stretches untouched. Second, insurance. Most commercial kitchen policies require evidence of TR19-compliant cleaning; if the work was not to standard or the records do not stand up, an insurer has grounds to dispute a claim - even if the fire did not start in the extract system, because spread through a greasy duct can be pinned on poor maintenance.
Third, the certificate itself. A cheap clean often skips the verification testing and the register entry that make a certificate defensible. What you are left with is a piece of paper that asserts the system is clean but cannot show against what, cannot prove the concealed runs were reached, and quietly overstates the scope. It reassures until it is examined, and then it does not protect you at all.
How the gamble usually plays out
The familiar story runs like this. A kitchen takes the lower of two quotes because the provider promises the same service for less. Months later an insurer or inspector asks for proof, the official post-clean report is not there, and the clean has to be done again by a compliant contractor - at full price. The bargain clean ends up costing far more than the quote it undercut, sometimes several times over. The lesson is not that price does not matter; it is that price without proof is a risk, not a saving.
It is worth being clear that a fair, keen price from a compliant contractor is not the risk here. The risk is a price that is low because the job is smaller than it looks - narrower scope, assumed access, skipped verification. Those are the corners that come back.
Judging the risk before you book
You do not have to be an expert to weigh this. Ask what the price covers: the whole system or just the canopy; whether the result will be verified below the standard and how; whether the certificate will read full or partial; and whether the clean will be registered so it can be checked. A contractor confident in their work will answer plainly. One that cannot - or that dodges the scope while emphasising the price - is asking you to gamble. Decline that bet; the stakes are too high for the size of the saving.
Questions
A keen price from a compliant contractor is fine. The risk is a price that is low because the job is smaller than it looks - narrower scope, assumed access, skipped verification. Those corners tend to come back.
Fire safety, because grease left in concealed runs is what a fire spreads through; insurance, because a claim can be disputed without compliant work and records; and the certificate, which may not hold up when examined.
Yes. Most policies require evidence of TR19-compliant cleaning. If the work was not to standard or the records do not stand up, the insurer has grounds to dispute - even if the fire started elsewhere, since spread through greasy ductwork can be attributed to poor maintenance.
The common pattern: an inspector or insurer later asks for proof, the official report is not there, and the clean is redone properly at full price. The bargain job then costs far more than the quote it undercut.
Ask what the price covers - whole system or just the canopy, how the result is verified, whether the certificate reads full or partial, and whether the clean is registered. Clear answers mean a real job; dodged scope means a gamble.
